Published:2011/7/5 1:14:00 Author:chopper | Keyword: audio, power amplifier | From:SeekIC

Figure shows the audio power amplifier. The circuit uses a high-voltage, internally-compensated integrated operational amplifier MC1536 .When the supply voltage Vs = ± 36V, the swing amplitude of output voltage is up to ± 30V, the maximum available supply voltage is up to ± 40V, input bias current is small (about 20nA below).The input offset current is less than 3nA, open-loop differential-mode gain is up to 5 × 106 (typical value). The chip is suitable for low-frequency amplification.
